3 Function and system design Measuring principle The Nivotester monitors the Soliwave FDR50/FQR50 microwave barrier s open collector output and uses a relay (change-over gate) to provide this output for many user applications. An LED displays the switching state of the relay. Problems such as a cable breakage are also displayed. The input on the Nivotester is galvanically isolated from main power and output. It is connected to the microwave barrier via a three-wire cable (ring or star wiring), whereupon the Nivotester provides distribution (intrinsically safe circuit, DC) voltage to the microwave barrier. Measuring system Emitter Receiver Nivotester The complete measuring system for limit detection consists of: an emitter FQR50, a receiver FDR50 and an evaluator Nivotester Optical or acoustic signallers, contactors, relays, solenoids etc. may be connected to the Nivotester. Limit switch signal function The appropriate setting for the limit switch signal function (see page 9) ensures that the relay for signal output and fault is always activated (fail-safe mode) in idle state. In combination with the Soliwave FDR50/FQR50 microwave barrier the following secure modes are possible: The relay drops out when the switch point is reached (microwave barrier interrupted), a fault occurs or the distribution voltage fails. The relay drops out when the switch point is underrun (microwave barrier uninterrupted), a fault occurs or the distribution voltage fails. Function monitoring system The Nivotester is equipped with a function monitoring system for improved fail-safe operation. A fault is indicated by an LED, the fault relay falls off. In combination with the microwave barrier Soliwave FQR50/FDR50-C* and -D* resp. the Nivotester -B* and -D* resp. can recognise the following faults and use an LED to indicate them: Breakage in the power supply cable to the emitter FQR50 Microwave barrier power input (emitter FQR50 and/or receiver FDR50) too high Short-circuit (emitter FQR50, receiver FDR50 or wiring) Manual function monitoring can be carried out by pushing the test button. 3
